This is really an update to the great answer from A. Rodas for use with Python 3.4 and Tcl 8.6 (I don't have enough reputation points to comment).

Set the environment variable TCL_LIBRARY in your activate script. On Windows (Python 3.4 with Tcl 8.6), just add this line to Scripts\activate.bat:

set "TCL_LIBRARY=C:\Python34\tcl\tcl8.6"

I came across this issue while using Windows 7, Python 3.4, and ggplot in a virtual environment.
